  1. ShockNature’s prelude to death 2008 Cycle “A” OEC Refresher

  2. Goals and Objectives • I Can: • Define shock. • List the early and late signs of shock. • Describe the treatment for shock.

  3. What is Shock? • Inadequate perfusion… • …What does this mean? • Lack of oxygen, other nutrients to body cells • The body needs oxygen to survive!

  4. Blood Pressure • What brings oxygen to body tissues?? Blood • What supports the delivery of blood?? Blood Pressure

  5. Shock • What is really happening in shock?? There is not enough blood pressure to adequately get oxygen to body tissues.

  6. Shock • How do I identify that a patient is in shock?? • Compensated Shock • Tachycardia • Tachypnea • A narrowing of the difference between the systolic and diastolic blood pressure (a.k.a - pulse pressure)

  7. Shock • How do I identify that a patient is in shock?? • Decompensated Shock • A drop in the systolic blood pressure

  8. Shock • Once the patient is in decompensated shock body cells begin to die. • This is a bad thing!!!! • Identify shock early before the patient has decompensated.

  9. Types of Shock • Hypovolemic:not enough volume • (e.g., bleeding, dehydration, vomiting, diarrhea) • Cardiogenic:not enough strength to push the volume • some causes of respiratory shock are actually cardiogenic shock (ex. Flash pulmonary edema from congestive heart failure)

  10. Types of Shock • Neurogenic(a.k.a. - Distributive): loss of tone in the blood vessels • (e.g., sepsis, severe infection, anaphylaxis, spinal cord injury, psychogenic) • Other reasons for shock: • A mechanical obstruction that prevents movement of blood(a.k.a. – Obstructive) • some causes of respiratory shock are actually obstructive shock • (ex. pulmonary embolism)

  11. Hemorrhage • A cause of hypovolemic shock • In trauma, hemorrhage most common cause of shock !!!! Caution:It is not the only reason for shock in trauma, but is definitely the most common reason.

  12. Hemorrhage • External • Internal • Chest • Abdomen • Pelvis • Where can a patient bleed to death?

  13. Shortness of breath Dizzy Pain Nausea Tachycardia Tachypnea Diaphoresis Pale Drop in systolic blood pressure (late finding) Signs & Symptoms of shock • Signs • Symptoms Don’t Forget to Look for Bleeding!

  14. OEC Management of Shock • Hemorrhagic Shock • Direct pressure • Elevation • Pressure points • Tourniquet (as a last resort) External Bleeding

  15. OEC Management of Shock • Hemorrhagic Shock • Determine if this it occurring • Safely and rapidly transport Internal Bleeding(chest, abdomen, pelvis)

  16. OEC Management of Shock: all types • Diagnose shock early • Stop bleeding • Give oxygen • Keep patient warm (Hypothermia makesshock worse) • Transport

  17. Remember… • See a drop in BP? You are way behind the eight ball! • Diagnose shock early • Direct pressure to stop bleeding • Give oxygen • Keep patient warm • Transport to definitive care
